Any designs using these plug clamps, I've been crediting as the 'Johan' rig. Johan originally sent in his DIY DSLR idea found here, and it's been a hit. I even have my hands on these clamps trying to put together my own.
Here's one very cool looking DIY DSLR rig from Derek out in Detroit, with some fancy Carbon rods purchased from DragonPlate.com. Carbon rods? Nice touch! Shoulder pad and Grips are still on it's way, but Derek wanted to give us an early sneak peek. I can attest that even with my Fiberglass Tent Poles, these clamps are strong. Check out Derek rocking what looks like a 70-200mm on this setup, proving to be a structure more than adequate for smaller cams. Great job Derek, thanks for sharing.
